Sean Slater's impact will be felt once again in Albert Square when actor Robert Kazinsky returns to EastEnders.
Robert, 35, reprises his role in the soap after more than 10 years away, and wastes no time in causing upset.
In Monday night's episode, Jack Branning is left fretting when Amy disappears from school.
However, unbeknownst to Jack, Sean has picked Amy up.
It remains to be seen how Jack and Sean's sister Stacey Slater react once they discover Jack is responsible...
Sean's return comes as his mum Jean (Gillian Wright) has been trying to contact him, as she battles ovarian cancer.
EastEnders continues Monday at 8:00pm on RTÉ One and BBC One.
